Council Grove State Park sits along the Clark Fork River in Missoula County, Montana, where a striking stand of ancient cottonwood trees marks the site of a historic council between Governor Isaac Stevens and the Salish people in 1855. At 187 acres, this compact park packs remarkable natural and cultural significance into a manageable footprint.

The towering black cottonwoods — some of the largest in Montana — create a dense canopy that feels almost cathedral-like, particularly in autumn when the leaves turn brilliant gold against the big Montana sky. The park’s riverside location makes it a natural corridor for wildlife, and visitors regularly spot white-tailed deer, osprey, great blue herons, and the occasional bald eagle fishing the Clark Fork.

Hiking trails wind through the cottonwood groves and along the riverbank, offering easy walks suited for families and casual explorers. Birdwatching is exceptional here, especially during spring and fall migrations. Fishing access to the Clark Fork provides opportunities for trout, and the calm stretches of river near the park are popular for kayaking and floating during summer months.

The park functions primarily as a day-use area, so plan accordingly if you need overnight accommodations — Missoula is just a short drive away with plenty of options.

Visit in late September through mid-October for peak fall color, or come in late spring when the river runs full and the cottonwoods leaf out. Summer brings warm afternoons perfect for riverside picnics, though weekends can draw crowds from nearby Missoula.
